Office Action

§103
Detailed Action The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . The Office Action is in response to claims filed on 4/9/2026 where claims 1-20 are pending and ready for examination. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The examiner has reviewed the Applicant’s arguments submitted on 4/9/2206. The examiner has withdrawn the 35 USC 112b rejection. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-2, 9, 11-14, 16 – 21, and 28 are rejected under 35 USC 103 as being unpatentable over Gan (EP 4358431) in view of Luo (US 20180098263) Regarding claim 1, Luo discloses a method comprising: receiving at a device, a first plurality of data packets (Gan; The receiver/receive end receives SL PDUs form the transmit end ([0176])4. SLC PDUs are the data units/packets being received. Item 4 ({0176]) also says “each time the transmit end sends an SLC PDU ...” So over repeated operation, the receive end receives a plurality of SLC PDUs/data packets); transmitting, by the device, a plurality of acknowledgement packets, one acknowledgment packet per data packet (Gan; Gan teaches ([0176]) the receive end sends feedback immediately after receiving an SLC PDU. Item 4 ([0176]) “Each time the transmit end sends an SLC PDU, the transmit end waits for an ACK from the receive end”) which equates to one CK for each SLC PDU; Accordingly, for each received SLC PDU, the received end sends an ACK feedback which is equivalent to plurality of acknowledgment packets, one per data packet;) and after transmitting the plurality of acknowledgment packets, negotiating, by the device, to perform muti-packet acknowledgment (Gan; Gan teaches after operating in stop and wait mode where the receive and sends an ACK for each received SLC PDU, the terminal negotiates a feedback mode with the network device, and the negotiated feedback mode may be the parallel feedback mode in which the receive end accumulates multiple SLC PDUSs and then seeds feedback. That is negotiating to perform multi-packet acknowledgement; Gan teaches stop and wait feedback mode where each received SLC PDU is individually acknowledged. The reference also teaches parallel feedback mode where multiple received SLC PDUs are accumulated before feedback is sent. Gan then teaches that the terminal negotiates with the network device about a feedback mode. Because the negotiated feed mode includes the parallel feedback mode, the negotiation si to perform multi-packet acknowledgement; see e.g. [0176] “... In parallel feedback mode, after receiving the SLC PUD sent by the transmit end , the receive end accumulates received SLC PDUs of a specific amount of data, and then sends the feedback information to the transmit end ...” See e.g. [0202] “Therefore, the transmit end may negotiate the acknowledgment mode with the receive end based on the total frame quantity field and the frame sequence number filed in the frame header information of the data frame. In this way, when the transmit end negotiates the acknowledgment mode with the receive end, additional frame header overheads may not be required”) As evidence of the rationale above, Luo discloses: multi packet acknowledgement (Luo; see e.g. [0086] In summary, the central node (hub) 721 acknowledges the reception of multiple packets 706, 708, 710, 712 . . . 771 from different nodes 750, 752, 754, 756 . . . 770 together by a single ACK packet 904 as shown in FIG. 10.

The motivation being the combined solution provides for incorporating a known technique resulting in increased efficiencies of delivering network traffic. Therefore it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Luo’s multi packet acknowledgement element. The motivation being the combined solution provides for implementing a known technique resulting in increased efficiencies of managing network traffic Claim 26 is rejected under 35 USC 103 as being unpatentable over Gan in view of Luo and in further view of He (US 20200244528) Regarding claim 26, Gan in view of Luo disclose the method of claim 1, Gan does not expressly disclose negotiating to perform multi-packet acknowledgment is performed in response to determining that a throughput of a communication link between the device and the another device is above a predetermined threshold. He discloses: in response to determining that a throughput of a communication link between the device and the another device is above a predetermined threshold (He; see e..g [0082] “... the link quality or traffic load for the UE has changed when a difference between a first traffic rate (e.g., a maximum throughput) based on an average MCS and a number of configured transmission/reception occasions differs from a second traffic rate (e.g., an actual data rate) based on average received data satisfies a threshold ...”) Therefore it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate He’s threshold scheme. The motivation being the combined solution provides for implanting a known technique resulting in increased efficiencies in delivering network traffic. Gan in view of Luo and in further view of He disclose: negotiating to perform multi-packet acknowledgment is performed in response to determining that a throughput of a communication link between the device and the another device is above a predetermined threshold (The combined solution per Gan ([0176] and He)) Therefore it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Luo’s multi packet acknowledgement element. The motivation being the combined solution provides for implementing a known technique resulting in increased efficiencies of managing network traffic Claim 27 is rejected under 35 USC 103 as being unpatentable over Gan in view of Luo and in further view of Kumagai (US 2023037909) Regarding claim 27. Gan in view of Luo disclose the method of claim 1, Gan does not expressly disclose wherein negotiating to perform multi-packet acknowledgment is performed in response to determining that an instruction from a higher layer has been received. Kumagai discloses: in response to determining that an instruction from a higher layer has been received (Kumagai; see e.g. [0072] “... Alternatively, conditions such as a transmission timing of the HARQ-ACK (or PUCCH) (for example, K0) may be configured by higher layer signaling (for example, dl-DataToUL-ACK”) Therefore it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Kumagai’s high layer signaling. The motivation being the combined solution provides for implanting a known technique resulting in increased efficiencies of delivering network traffic. Gan in view of Luo and in further view of Kumagai disclose: wherein negotiating to perform multi-packet acknowledgment is performed in response to determining that an instruction from a higher layer has been received (The combined solution per Gan and Kumagai). Therefore it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Luo’s multi packet acknowledgement element. The motivation being the combined solution provides for implementing a known technique resulting in increased efficiencies of managing network traffic Any inquiry concerning this communication or earlier communications from the Examiner should be directed to TODD L.
